Abstract

The invention relates to a device for simulating overhead line fault caused by insulator pollution defect. The device comprises a simulation operation platform and simulation electric poles. An insulated wire is arranged between the simulation electric poles. The insulated wire is provided with an insulator. The simulation operation platform is provided with a spraying mechanism. Salt water or dust is sprayed onto the surface of the insulator by the spraying mechanism to simulate insulator pollution defect. The simulation operation platform is provided with an ultrasonic wave. The device has the advantages that the insulator pollution defect is simulated by spraying the salt water or dusts onto the surface of the insulator through the spraying mechanism, different degrees of pollution defects of the insulator can be simulated by controlling the amount of salt water or dusts on the surface of the insulator, and overhead line fault caused by the insulator pollution defects is verified through partial discharge of the ultrasonic wave carried on the insulated wire, thereby enabling operation and maintenance personnel and operators to quickly and accurately obtain the influence of the insulator on the overhead line fault under different degrees of pollution defects, facilitating later analysis and improving operation and maintenance efficiency.

Description

technical field [0001] The invention relates to a device for simulating faults of overhead lines caused by pollution defects of insulators. Background technique [0002] Overhead lines mainly refer to overhead open lines, which are erected on the ground. They are transmission lines that use insulators to fix the transmission wires on the towers standing on the ground to transmit electric energy. (such as strong winds, lightning strikes, pollution, ice and snow, etc.) and cause faults. At the same time, the entire transmission corridor occupies a large area of ​​land, which is likely to cause electromagnetic interference to the surrounding environment, and the pollution of insulators is likely to affect the faults of overhead lines. The existing operation and maintenance Personnel cannot grasp the probability of failure of insulators on overhead lines in different degrees of polluted environments, which makes operation and maintenance personnel unable to repair overhead lines...
